Did the design run?

every check held
  • Run completed: heldharness.run-completedThe environment was built, the architecture returned and grading finished, none of them throwing.
  • No API failures: heldharness.apiNo model call failed at the API.
  • Every call ended: heldharness.calls-endedEvery call ended with a result, or was stopped by the run's own limits.
  • No harness tool denied: heldharness.harness-toolsThe sandbox guard never denied a harness tool, nor a tool the session itself offered.
  • Tool servers connected: heldharness.mcp-connectedEvery tool server the harness gave a call was connected when the session started.
  • No foreign tool servers: heldharness.mcp-hermeticNo call loaded a tool server the harness did not give it.
  • Builtin tools: heldharness.builtin-toolsA check recorded with the run.
  • Structured replies arrived: heldharness.structured-outputEvery call that asked for structured output and ran to the end got it.
  • No silent fallbacks: heldharness.not-degradedNo phase fell back on a default (an empty plan, a default winner) instead of its output.
  • All three proposers ran: heldpropose-select.proposalsThree proposers ran in parallel, each from its own angle, and none was starved while another ran.
  • The selector chose: heldpropose-select.selectionThe selector picked a proposal by a valid number, read from its schema reply and not a default.
  • Each call was shown the right tools: heldpropose-select.toolsEach proposer was shown the read-only tools, the selector none, and the executor the full toolset.

The call-by-call replay is not published for this run. Traces are large, so the repository keeps 9 of this run set’s 900 and leaves the rest out; the score, phases and final answer on this page come from the committed run record.

Final answer

Perfect! All actions have been executed successfully. Here's what was completed:

Summary

Task completed for Marcus Ade (C-200) on order O-2003:

  1. ✅ Cancelled line L1 (Wireless Mouse - P-MOU, qty=2)

    • Line status changed from pending to cancelled

  2. ✅ Refund issued to card

    • Amount: 7,350 cents (the full amount the customer paid for the line)
    • Method: Original payment card
    • Refund reference: RF-1

  3. ✅ Inventory restored

    • P-MOU stock increased from 30 to 32 units
    • The 2 cancelled units were returned to warehouse stock

Rest of order unaffected:

  • Line L2 (Hub - P-HUB, qty=1) remains pending
  • Line L3 (Cable - P-CAB, qty=3) remains pending
  • Both will ship as planned
  • Order status remains pending

The cancellation follows domain policy: since the line had never shipped, it was treated as a cancellation (not a return) and refunded to the original payment method for the full amount paid.
